abstract：:Among DNA repair pathways, nucleotide excision repair (NER) is able to recognize and process a wide variety of DNA lesions. The NER mechanism can be summarized in two stages: incision/excision of the lesion and DNA repair synthesis. Here, we have assessed the repair synthesis activity of protein extracts from differen...

abstract：:The uncoupler-induced inactivation of H+-ATPase in hepatoma 22a and mouse liver mitochondria has been studied. The dependence of this process on delta microH, and pH and ATP was established. The inactivated ATPase could be reactivated at alkaline pH values in the absence of ATP. These data indicate that the inactivati...

By employing short hairpin (sh)RNA-dependent knockdown approach, we demonstrate that lymphotoxin α (LTα) is a target of posttranscriptional gene regulation by HuR in hepatocellular carcinoma (HepG2) cells. Consequently,...
